I know the m9 doesn't support wireless charging out of the box, but I do know you can buy a wireless charging pad.
I was planning on buying this bundle https://www.amazon.com/dp/B010G0ENCE/ref=cm_sw_r_other_awd_MISqwb6MHJ6SH
Does anyone think wireless charging is worth it?

Since you're asking for opinions rather than experience in the product, I recommend steering clear of wireless charging - especially given the extra lengths needed to make it work on the M9. I've used wireless charging with my Nexus 7 (2013), and while it was convenient, it only saved me those couple of extra seconds to plug it in.... but lost that advantage due to the slower charge time of induction chargers.
I have a certified fast charger for my phone and find that it was well worth the price and does indeed live up to its name.
My wife and I are getting new phones this year, and we really like the look and feel of the Ascend Mate 7, and in my research efforts, I found an interesting prospect. I love doing research, especially before I buy a new phone. The biggest reason for the upgrade (at least in my case) is to have the ability to use NFC again, more specifically wireless charging. My wife is using a Note 3 that I bought a Qi wireless charging receiver for, and so far it's worked flawlessly. I on the other hand have the Mate 2, which as you know doesn't have any NFC capabilities at all. Recently I have been reading about how the Mate 7 has NFC, but doesn't allow for wireless charging. I found a number of reasons from because of the back cover being metal it would block the signal, to they don't make a wireless receiver for the device, and among others, but I found something interesting that might solve the problem.
I opened up my Amazon Shopping app this morning, and I saw the 'Micro USB Universal Wireless Charger Receiving Patch' in my recommendations list. The description it gave for the item is that as long as your device has a micro USB charging port, this will give any device the ability to wirelessly charge on any Qi wireless charging pad. My first reaction was to jump for joy because I had solved the problem by which also sealing the deal of upgrading to the Mate 7. Here is where I think there may be a snag though. There are quite a few of these on Amazon that all do the same thing, some even come with a Qi wireless charging pad included, but they are all from brands that I've never heard of, and I myself being a very critical person am really on the wire. I hate wasting money, and I'm sure that I am not alone in saying that. So I want an opinion, because having the ability to not only use NFC again, but also the ability to wirelessly charge my device would make me a very happy man. I also love writing, so excuse the long post. Thank you in advance.
I think that would just be a phone cover with a charge coil built into the back and always plugged into the USB port. They'd be available for many phones. It may interfere with NFC, not sure.
A phone cover would have been a bonus, but nothing like that exists for the Mate 7 that I've seen. No this is a stand alone, very thin device. The description definitely details it correctly, it literally looks like a patch. I would post a link, but the app won't let me until I post a certain number of posts. Traditional Qi wireless charging receivers look similar, but they have adhesive fixed to the under side that allows you to attach it to the battery, and they have gold contacts that you match up with the contacts on your respective device. This has a long-ish strip that has a male micro USB attached at the end that plugs in to your device, and you can either permanently affix the patch underneath the back cover of your phone, or allow it to rest on the back cover.
ATTEMPTED HARDWARE MODDING - the title may be a bit misleading
Longtime Note series diehard fan here. I absolutely cannot live with wireless charging, that's even more important to me than removable batteries, I have had 2 phones have constant problems with wear on the USB port, and my lifestyle is already adapted around Qi charging, I have multiple wireless charging pads, and have, for the past year, never plugged in a USB cable into my Note 3 except for flashing roms and copying backups to my Thinkpad. Now, I am considering a new phone, and my options are either the LG V20, which has no wireless charging but a removable battery, or an S7 Edge with wireless charging and no removable battery.
As title says, I am interested in getting true wireless charging for the LG V20, not some crappy plug-in wireless charging adapter crap. What I'm thinking is finding some point on the motherboard, most likely on the positive and negative terminals of the charging port, and soldering wires to it, and the wires would be soldered to the exposed contact points of an old Samsung Note 3 wireless charging add-on. The same idea has been implemented in a Oneplus One successfully before. Now, obviously, if there were the wireless charging reciever, the metal back cover would be interfering with it. So instead, I will buy a cheap TPU case so that I protect the battery but allowing Qi charging to pass through. Please chime in, and let's facilitate a discussion here. Also, there have been previous threads discussing this idea, including a thread where LG customer service apparently confirmed that LG was planning a wireless charging accessory (in Jan 2017), obviously take this with a grain of salt. The general idea is that either customer service was giving us a load of crap, or LG V20 has the hard ware to do so, but LG never bothered to develop it.

Also, something else to note, would wireless charging be Qi or PMA standard? Back in the LG G3 days, the AT&T and Canadian versions (which was basically the same phone) had a PMA reciever, whereas Verizon and other variants used Qi.

Possibly varying by region, but very possibly both. While Qi seems to be ahead there are now quite a number of chips which implement both, attempting to figure out which standard the other end uses and adapting. Since consensus is only emerging slowly that looks like the way things are going to end.

Ok, thanks for replying. So now, the question is, how to proceed? Should we try to implement the mod like the OPO I was discussing in the original post? Or should we try to find the necessary software and hardware to enable purported built-in wireless charging? I personally am in favor of trying to solder a Qi receiver onto the charging port, as my main goal is reduce plugging a cable into the USB port so much, but maybe there is a more elegant solution?
I have attached a picture below with the NFC contacts circled. Do you see any points on the motherboard which could potentially be wireless charging contact points? Or are people suggesting that those 10 random metal dots distributed around the phone, are the wireless charging contact points? Because that would just be hella weird.
Post #19 on this thread is what I'm referring to for a reference image: https://forum.xda-developers.com/v20/how-to/lg-v20-wireless-charging-support-t3486488/page2
Also, here are some pictures of charging ports for LG V20. Do you see anywhere that could potentially be used to solder wires on, to attach to a 3rd party Qi receiver? Personally, I am guessing that only the AT&T variant will be Powermat, everything else, like int'l or Verizon variants will support Qi standard. Knowing LG and their tendency to reduce a load of regional variants with random differences (like the LG G6 wireless charging/DAC/64gb storage debacle).
Another wireless charging thread. Pic on page 2. https://forum.xda-developers.com/v20/help/lg-v20-wireless-charging-t3471387/page2
Anyone else have anything to comment on? If not, I'll probably just solder wires to my charging port once my LG V20 arrives off of aliexpress (which might be a while)
I just got my v20. I'll be poking at it over the next couple of days to see what those points actually do.

Hey, that's great! I have access to AutoCAD inventor, so if you can provide me with the exact dimensions I could try to make a 3D printed model of a non-metal LG V20 back cover, over Christmas break. Hopefully I will have time...
I didn't get anything obvious when I checked with the multimeter. I'm going to probably tear this down on Monday and see if I can find anything conclusive. See if the traces from those points go anywhere.

Ive had a look inside my phone and most of the pins seem to be for grounding, connected through a resistor or capacitor. I dont believe there is any pins for qi charging. Look at the pins for the nfc, they are located close to one another, the rest are spread out at almost regular intervals to provide grounds for the battery cover. Also, i dont think connecting a qi receiver to the usb is a good idea, it may confuse the port into thinking an accessory is connected, and i dont think the receiver would like getting backfed 12v when you connect the phone to a QC charger. I think Real qi charging seems unviable for the v20, Unless someone has a service manual to check the schematics.

I wish I had seen this before taking my phone apart. I didn't see anything from the pins going to any of the chips on the board either. Dunno why they skipped wireless charging on the v20.
Hi,
The idea of qi receiver for pixel XL is good but it's not easy to remove the receiver if you want a quick charge using the cable. Has anyone found something like easy removal qi receiver or not or like a USB pass through option. Otherwise, each time, we need to remove the case and adhesive receiver will either get damaged or lose it's function. I have found below idea but not much reviews to judge. Any opinions?

Hi,
I want to retrofit wireless charging capability with one of those thin receivers you can put between your phone and the case and then plug into the usb port. The only thing that worries me is a coil or antenna or something which is sitting on top of the battery. I can be seen in this disassembly video: https://youtu.be/kNzDbb-lJzs?t=42 This would probably be covered by the added receiver. What is this? Would covering this up be a problem?

NFC.
It doesn't seem like a good idea to me.
Mhm, ok. If I don't want to use NFC anyway would this be a problem? I mean, the phone should be able to handle beeing placed on a qi charging station (if someone is ignorant that it does not have this function) without induction of any harmful currents into that antenna, right? So I would just loose the NFC functionality if I shield it with the receiver patch.

My reaction was not about NFC, it is even possible that it will continue to work, maybe it will be less sensitive. I just expressed my opinion that I personally dislike your intention, because I don't think wireless charging is a killer feature for the ZF6 that we have to regret not having. Moreover, our battery size and space in which it is located and cooled, and so on is not at all adapted for continuous wireless charging and higher charging temperature.
After all, we don't charge so often with our big battery, and when you charging by cable, you charge more environmentally and faster than with the best wireless charger. That is to be remembered, and that is what I meant and what was my point.
For me NFC and big battery are killer features, but wireless charging isn't.

OK, I am getting your point. I just bought this phone, and was not used to having a battery that can go two days easily. I have qi chargers scattered around everywhere (car, office, living room ...) to top up my battery whenever I lay my phone down somewhere. That is starting to seem a bit pointless. I just discovered the function to slowly (and therefore least damaging to the battery) charge and reach 100% at a specified time. Perfect for overnight charging.
Let's give it a few more days to see if I still feel the urge to retrofit wireless charging.
But from the purely technical standpoint, I had another thought. The qi charger only switches on the charging field when it detects a compatible device set down on it. So it would not do that if an untouched Zenfone 6 would be placed on the charger, and there would not be any danger of inducing currents into the NFC antenna and damaging something. Now, if I retrofit a charging pad the charger actually does produce a field when the phone is on it, thats the whole point. No idea how much current would actually be inducted in the NFC antenna, but I am very certain it is not zero. Does someone have the technical background to at least make a guess?
